I\'m starting to learn Haskell by doing the 99 Haskell problems.http://www.haskell.org/haskellwiki/H-99:_Ninety-Nine_Haskell_ProblemsI\'d like to write tests for each program/function using quickcheck
Backstory I\'m porting the QuickCheck unit test framework to C (see the working code at GitHub). The syntax will be:
Does anyone know exactly how to define a generator in Haskell using QuickCheck such that chosen elements are picked only ONCE?
Are there any extensions to HUnit or QuickCheck that allow a continuous integration system like Bamboo to do detailed开发者_运维问答 reporting of test results?
In various more functional based languages there are tools (like Quickcheck) which allow for property based testing.
I am using QuickCheck v1. Here is a simple prop_xxx defined as below: prop_foo :: (Num a) =>[a] -> Bool
installed QuickCheck, i install againcabal install QuickCheck-1.2.0.0 and load ag开发者_如何学运维ain and has error
I have some old Haskell code that includes QuickCheck test cases.Newer versions of QuickCheck (I\'ve just upgraded to 2.4.0.1) include type class instances for Arbitrary Word8 and others.These did not
I\'m trying to write a QuickCheck property that takes one or more functions as input.To keep things simple, consider a property to check that function composition is equivalent to successive function
